EM4126- EPC and UHF ICs

Read/Write, EPC Gen2 / ISO 18000-63 Type C Passive RFID IC

General Description

EM4126 is a UHF RFID IC compliant with both ISO/IEC 18000-63 (formerly known as 18000-6 Type C) and EPCTM Class-1 Generation-2.

The EM4126 has 224 bits of non-volatile memory (16 bit PC Word and 208 bit UII/EPC Code) enabling the support of ISO or EPC data structures.

EM4126 achieves a typical read sensitivity of -19 dBm at the chip level, which translates into a typical -21 dBm sensitivity at the tag level for a dipole-like antenna with 2 dBi gain (25us TARI, 250 kHz BLF).
